Class AuxiliaryTable (3.14.0rc0)

AuxiliaryTable(mapping=None, *, ignore_unknown_fields=False, **kwargs)

An auxiliary table contains statistical information on the relative frequency of different quasi-identifiers values. It has one or several quasi-identifiers columns, and one column that indicates the relative frequency of each quasi-identifier tuple. If a tuple is present in the data but not in the auxiliary table, the corresponding relative frequency is assumed to be zero (and thus, the tuple is highly reidentifiable).


Required. Auxiliary table location.
quasi_ids MutableSequence[]
Required. Quasi-identifier columns.
Required. The relative frequency column must contain a floating-point number between 0 and 1 (inclusive). Null values are assumed to be zero.



QuasiIdField(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A quasi-identifier column has a custom_tag, used to know which column in the data corresponds to which column in the statistical model.
